Amir can find some useful advices (and related formulae) on one-way ANOVA
with repeated measures in:

Chow SC, Shao J Wang H. Sample size calculations in clinical research.
Second Edition. Boca Raton, FL: Chapman & Hall/CRC: 389-394.

Dear statalisters

How do I use stata to randomize the subjects to more than two groups for
repeated measures but in a way that I assign two subjects to treatment group
and one to control. For example treatment A 20 subjects, Treatment B 20 and
control 10 subjects with 4 follow up time points. I am not sure if  sampsi
or fpower can handle it. 

many thanks
